ABP法在高密度电阻率法反演中的应用

非线性反演方法作为地球物理反演的一个重要分支,在地球物理反演中发挥着特有的作用.近年来学者对非线性联合反演研究较多,但目前仍未有实质性的研究进展;本文尝试利用BP(Back Propagation)神经网络优化方法与蚁群算法联合演算,实现高密度电阻率法的电阻率二维非线性反演.通过两组模型的结果比较,BP与ABP 法的反...

The application of ABP method in high-density resistivity method inversion

As an important branch of geophysical inversion, non-linear inversion method has played a unique role in geophysical inversion. In recent years, more researchers lay emphasis on non-linear joint inversion, but has not made any substantial progresses. This paper tried to achieve high density resistivity two-dimensional non-linear inversion by using the joint calculus of BP neural network optimization method and ant colony algorithm. A comparison of the results revealed that the ABP method is much better than BP neural network inversion method, the former can overcome the deficiencies of BP neural network inversion method, reduce the number of iterations, save computing time and finally obtain a better inversion result.
